On Infinite-Dimensional Algebras of Symmetries of the Self-Dual Yang-Mills Equations
Full text linkInfinite-dimensional algebras of hidden symmetries of the self-dual
Yang-Mills equations are considered. A current-type algebra of symmetries and
an affine extension of conformal symmetries introduced recently are discussed
using the twistor picture. It is shown that the extended conformal symmetries
of the self-dual Yang-Mills equations have a simple description in terms of
Ward's twistor construction.Comment: 10 pages, LaTeX, final version (to appear in J.Math.Phys.
